DETAILED DESCRIPTION
[0032] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.
[0033] The following describes the drilling box sliding conveying device according to an embodiment of the present invention in conjunction with the accompanying drawings.
[0034] like Figures 1 to 4 As shown, the drilling box sliding conveying device of the embodiment of the present invention comprises: a support frame 1, a cylinder assembly 3 and a conveying assembly.
[0035] The support frame 1 is provided with a sliding frame 2 which is movable along its length direction. Both the support frame 1 and the sliding frame 2 are composed of a bottom plate, a top plate and a support plate connecting the two. The support plate of the support frame 1 is a telescopic plate. The telescopic design allows the position of the drill box 7 to be adjusted according to different construction requirements, thereby increasing the applicability and flexibility of the device. The sliding frame 2 moves between the bottom plate and the top plate of the support frame 1.
[0036] The cylinder assembly 3 has a primary moving part 302a and a secondary moving part 303a. The primary moving part 302a is connected to the sliding frame 2 so that the primary moving part 302a moves and drives the sliding frame 2 to move between the first end and the second end in the length direction of the support frame 1, that is, drives the sliding frame 2 to move between the bottom and the top of the support frame 1.
[0037] During the actual construction process, the top plate of the support frame 1 gradually extends out to contact the rock wall, and then the first-level moving part 302a extends out, so that the first-level moving part 302a drives the sliding frame 2 to move from the bottom of the support frame 1 to the top of the support frame 1, until the top plate of the sliding frame 2 contacts the top plate of the support frame 1, and then the secondary moving part 303a moves from the bottom of the sliding frame 2 to the top of the sliding frame 2.
[0038] The conveying assembly includes a chain 4, a connector 5 and a stopper 6. The chain 4 is rotatably arranged on the secondary moving part 303a, and the chain 4 is connected to the sliding frame 2 through the stopper 6, so that the chain 4 is driven to rotate during the movement of the secondary moving part 303a. The connector 5 is arranged on the chain 4, and the connector 5 is used to connect the drill box 7, so that the chain 4 drives the drill box 7 to move.
[0039] like Figure 2 As shown, in the initial state, the drill box 7 is located at the bottom of the device. Figure 3 As shown, in the working state, the drill box 7 is moved to the top of the device through the extension and retraction of the support frame 1, the extension and retraction of the cylinder assembly 3 and the rotation of the chain 4.
[0040] It is understandable that in construction such as underground engineering, tunnel excavation or slope stabilization, the height of the borehole may vary from the ground to a higher rock surface. The drill box 7 can be moved from the bottom to the top, which can ensure that effective drilling operations can be carried out at different heights.
[0041] Furthermore, the connecting member 5 and the limiting member 6 jointly divide the chain 4 into a first section 401 and a second section 402, and one end of the first section 401 and / or the second section 402 connected to the connecting member 5 is movable, and its moving direction is parallel to the straight part of the chain 4. By adjusting the position of the end of the chain 4, the tension of the chain 4 is adjusted.
[0042] Therefore, the drill box sliding conveying device of the embodiment of the present invention can adjust the tension of the chain 4 in real time according to actual construction requirements, thereby ensuring the stability and reliability of the feed movement of the drill box 7, improving construction efficiency, and reducing equipment failure rate.
[0043] In some embodiments, Figures 1 to 4 As shown, the connecting member 5 includes a mounting seat 501, a fixed block 502 and a movable block 503. The fixed block 502 and the movable block 503 are arranged on the mounting seat 501 at intervals, and the movable block 503 is movable on the mounting seat 501. The fixed block 502 is connected to the end of the first section 401 of the chain 4, and the movable block 503 is connected to the end of the second section 402 of the chain 4.
[0044] It can be understood that the tension of the chain 4 can be adjusted by adjusting the distance between the movable block 503 and the fixed block 502. For example, when the distance between the movable block 503 and the fixed block 502 increases, the tension of the chain 4 decreases. When the distance between the movable block 503 and the fixed block 502 decreases, the tension of the chain 4 increases.
[0045] Alternatively, if Figures 1 to 4As shown, the connecting member 5 further includes an adjusting bolt 505 and a supporting block 504. The supporting block 504 is arranged on the mounting seat 501, and the movable block 503 is located between the fixed block 502 and the supporting block 504. The supporting block 504, the movable block 503 and the fixed block 502 are respectively provided with screw holes for matching the adjusting bolt 505, so that the adjusting bolt 505 rotates and drives the movable block 503 to move, thereby improving the convenience of adjusting the tension of the chain 4.
[0046] Furthermore, a fastening nut 506 is provided at the end of the adjusting bolt 505, and the fastening nut 506 is located on the side of the supporting block 504 away from the movable block 503. When the tension of the chain 4 is adjusted, the fastening nut 506 is screwed and pressed against the supporting block 504 to fix the adjusting bolt 505 and improve the stability of the structure.
[0047] In some embodiments, Figures 1 to 5 As shown, a sliding hole 5011 is provided on the mounting seat 501 , and a guide column 201 penetrating the sliding hole 5011 is provided on the sliding frame 2 .
[0048] It can be understood that the drill box 7 is installed on the chain 4 through the connecting piece 5. When the chain 4 rotates to drive the drill box 7 to move, the guide column 201 is used to assist the movement, thereby improving the stability and safety of the movement of the drill box 7.
[0049] In some embodiments, Figures 2 to 9 As shown, the limiter 6 includes a clamping block 601, and a clamping slot is provided on the sliding frame 2, and the clamping block 601 is clamped in the clamping slot. The slot wall of the clamping slot and the clamping block 601 are provided with corresponding first mounting holes 602, and bolts are installed in the first mounting holes 602 to achieve detachable connection between the clamping block 601 and the sliding frame 2, which is convenient for maintenance operations.
[0050] Optionally, the block 601 is provided with two assembly grooves, which correspond to the first section 401 and the second section 402 of the chain 4. A moving block 603 is provided in the assembly groove, and a gap 604 is provided between the moving block 603 and the groove wall of the corresponding assembly groove, so that the moving block 603 can move within a certain range in the assembly groove. A second mounting hole 605 is provided on the moving block 603, so that the pin of the chain 4 is assembled in the second mounting hole 605.
[0051] The movable block 603 assembled on the second section 402 of the chain 4 has a gap 604 between it and the groove wall of the assembly groove, such as Fig. 9 In the position indicated in the figure, a force measuring element, such as a pressure plate of a sensor, is arranged in the gap 604 to detect the force condition of the second section 402 of the chain 4. Similarly, the force of the first section 401 of the chain 4 is also measured in the above manner.
[0052] Therefore, according to the detection result, the force of each section of the chain 4 is adjusted in real time to ensure that the force is consistent and avoid eccentric loading that causes excessive load on one side of the chain 4.
[0053] Furthermore, a baffle 606 is provided on the clamping block 601, and the baffle 606 contacts the pin shaft assembled in the second mounting hole 605, thereby playing a role in blocking the pin shaft and avoiding the problem of the pin shaft falling out during movement.
[0054] In some embodiments, Figures 1 to 3 As shown, the cylinder assembly 3 is arranged along the length direction of the support frame 1, and the cylinder assembly 3 includes a cylinder rod 301, a primary cylinder barrel 302b and a secondary cylinder barrel 303b.
[0055] One end of the cylinder rod 301 is connected to the bottom plate of the support frame 1, and the other end of the cylinder rod 301 is slidably installed in the primary cylinder barrel 302b. The two ends of the primary cylinder barrel 302b are respectively connected to the bottom plate and the top plate of the sliding frame 2, that is, the cylinder rod 301 slides through the bottom plate of the sliding frame 2 and is connected to the bottom plate of the support frame 1.
[0056] The secondary cylinder 303b is slidably mounted on the primary cylinder 302b. The length of the secondary cylinder 303b is greater than half of the distance between the bottom plate and the top plate of the sliding frame 2. The secondary cylinder 303b moves between the bottom plate and the top plate of the sliding frame 2.
[0057] It can be understood that the primary cylinder 302b is the primary moving part 302a of the cylinder assembly 3, and the secondary cylinder 303b is the secondary moving part 303a of the cylinder assembly 3. The cylinder rod 301 is extended so that the primary cylinder 302b drives the sliding frame 2 to move between the top plate and the bottom plate of the support frame 1, and the secondary cylinder 303b moves between the top plate and the bottom plate of the sliding frame 2.
[0058] Therefore, the drill box sliding conveying device of the embodiment of the present invention adopts a two-stage oil cylinder, which shortens the length of the oil cylinder and increases the shape of the oil cylinder, thereby improving the space utilization of the device.
[0059] In some embodiments, Figure 2 and Figure 3 As shown, both ends of the secondary cylinder 303 b are provided with mounting shafts for the chain 4 to surround, and a rotating member is provided between the chain 4 and the mounting shafts, thereby improving the rotation effect of the chain 4 .
[0060] For example, the rotating member is a guide wheel, and the chain 4 is wound around the guide wheel. Preferably, the rotating member is a roller bearing, and the chain 4 is wound around the roller bearing, and a positioning sleeve is provided on the side of the roller bearing close to the secondary cylinder 303b, and a retaining ring is provided on the side of the roller bearing away from the secondary cylinder 303b.
[0061] It is understood that the locating sleeve and the retaining ring can prevent the roller bearing from moving axially on the mounting shaft due to vibration or axial force, and prevent the bearing from falling off or shifting. The retaining ring and the locating sleeve also play the role of sealing the roller bearing, preventing lubricating oil from leaking, and maintaining the lubrication state inside the bearing.
[0062] In addition, by using cylindrical roller bearings instead of guide wheels, rolling friction replaces sliding friction, which greatly reduces the friction coefficient, reduces energy consumption, and also reduces wear and tear, extending the service life of the positioning sleeve.
[0063] In some embodiments, Figure 2 and Figure 3 As shown, the connection between the limiting member 6 and the sliding frame 2 is located in the middle of the sliding frame 2 .
[0064] It is understandable that setting the connection position between the limit member 6 and the sliding frame 2 in the middle of the sliding frame 2 is helpful to evenly distribute the force and reduce the structural deformation caused by the eccentric load, thereby improving the stability and service life of the entire mobile device.
[0065] And, if Figure 1 As shown, there are two conveying assemblies, which are respectively arranged on two sides of the secondary moving part 303a.
[0066] It is understandable that two conveying assemblies are symmetrically arranged on both sides of the secondary cylinder 303b. Such a design can ensure the balance of the drill box 7 during movement and reduce the shaking and noise caused by unbalanced weight.
[0067] Therefore, the optimization of the position of the limiter 6 and the symmetrical arrangement of the conveying components enhance the mechanical strength and durability of the entire device and adapt to the complex and changeable construction environment.

Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.
